Much like the Cosmic Microwave Background, the Cosmic Neutrino Background permeates our Universe and it could take us back to 1 second after the Big Bang. Today, we discuss the effect of the Sun on modulating the expected signal from the neutrino background.

The authors raise a key point about the detection of gravitational waves from the early universe. Not only would such a detection verify the theory of inflation, but it would also prove the quantization of gravity.
